The type of examination involving not only the affected area of the illness, but also other systems or related organs, is a ____.

The correct answer is a comprehensive examination. This type of examination goes beyond just assessing the affected area of illness; it involves evaluating the patient’s overall health and examining other systems or related organs that may be impacted by the primary condition.

A comprehensive examination typically includes a thorough review of the patient's medical history and a complete physical examination, encompassing multiple body systems. This holistic approach allows the healthcare provider to identify any related issues that might not be immediately apparent and ensures that all potential factors affecting the patient’s health are considered.

In contrast, a focused examination is primarily targeted towards a specific problem or area of concern, assessing only the affected region or system without exploring other related systems. The detailed examination tends to describe a more in-depth look than a concise evaluation but is still usually concentrated on particular issues rather than broad overall systems. A brief examination is even more limited and typically involves a quick assessment rather than an in-depth analysis. Therefore, the comprehensive examination is the most appropriate term for the described approach.
